Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a silver halide color photographic light-sensitive material, and relates to a silver halide color photographic material in which the storage stability of color images is improved by using an epoxy compound that is hardly soluble in water. Regarding materials. More specifically, the present invention relates to a silver halide color photographic material that uses the above compound to improve the fastness of yellow images to humidity and heat, and has excellent brown color reproducibility.

(Prior art) When preserving color photographic materials semi-permanently as records, it is necessary to minimize the degree of photobleaching and dark fading (suppressing the degree of fading and adjusting the initial color balance of the three-color fading of yellow, magenta, and cyan dye images). It is desirable to maintain this condition.

However, when stored in a humid environment, the yellow dye image fades to a greater degree than the other two colors, resulting in a significant deterioration of image quality.

Also, U.S. Pat. No. 4,540,654 and U.S. Pat. No. 4,882.
When the so-called pyrazoloazole magenta coupler represented by No. 266 came into practical use, it provided good sensitometry and good color reproducibility, especially for red, and color prints with less staining and excellent image storage stability. Now you can get it.

On the other hand, in conventional yellow couplers, the maximum absorption wavelength of the coloring dye formed is generally located on the long wavelength side of the absorption characteristics that are desirable from the viewpoint of color reproducibility, and the maximum absorption wavelength of the coloring dye formed is generally on the long wavelength side, and It has the disadvantage that absorption in the wavelength region does not sharply decrease to zero,
This was insufficient to obtain excellent color reproducibility for hues such as yellow and green. In order to solve such problems,
For example, it is conceivable to use a coupler that provides a yellow dye whose maximum absorption wavelength is on the relatively short wavelength side, as disclosed in JP-A-1-173499.

However, when using the above magenta coupler, especially a magenta coupler with a moderate coupling speed, and the above short-wave yellow coupler, the resulting color photograph has high density, low fog, and excellent brown color reproducibility; It was discovered that when color photographs are stored for a long time, the magenta density in the yellow image becomes high, which causes a problem of color mixing during image storage, and it was desired to maintain excellent color reproducibility even during image storage. .

In order to solve such problems, Japanese Patent Application Laid-Open No. 64-5004
No. 8, No. 64-50049 and JP-A-61-4041
The use of a cyclic ether compound or an epoxy group-containing compound is disclosed in the No. 1 issue, etc., but although these compounds are found to be effective to some extent in improving the dark fading of yellow dye images due to temperature and humidity, the improvement is not yet sufficient. Ta.

More specifically, it is an object of the present invention to provide a silver halide color photographic light-sensitive material in which fading of yellow images and magenta color mixture in yellow images during storage at high temperatures are improved, and which has excellent brown color reproducibility.

From Table 1, it can be seen that the samples of the present invention are excellent in color image storage stability and color reproducibility. That is, comparative sample 10
7 has improved color reproducibility compared to samples 101 to 106, but the color image storage properties such as fading of yellow and mixing of magenta in yellow deteriorates, and samples 108 and 109 have a base paper pH of 7.3. Using a paper support of 100 to 100 ml provides a slight improvement, but it is not sufficient.
